Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of indoor ventilation, and specifically relates to an indoor ventilation device for a stadium. BACKGROUND

[0002] A stadium is a building or facility specially designed for holding sports events and activities. The indoor part of a stadium mainly includes a spectator stand, a competition site, an athlete rest area, a media work area and the like. In order to ensure the comfort and quality of the indoor environment, a special indoor ventilation device is arranged in the stadium. The ventilation device can help maintain the circulation of indoor air, thereby ensuring the comfort of athletes and spectators during the competition and watching the competition.

[0003] A stadium intelligent ventilation device is disclosed in a utility model patent with the publication number CN218154663U and belongs to the technical field of ventilation equipment. The ventilation device comprises a ventilation duct. A character-shaped frame is fixedly arranged on the inner side wall of the ventilation duct. A hollow circular pipe is horizontally arranged at the center of the character-shaped frame. A filter pad is arranged outside the hollow circular pipe on the left side of the character-shaped frame. A fixed grid is arranged outside the hollow circular pipe on the left side of the filter pad. A transmission rod is arranged in the hollow circular pipe. A scraping brush is slidably arranged on the outer side wall of the left end of the transmission rod. A wind-driven propeller is arranged at the right end of the transmission rod. The ventilation device can collect and remove the accumulated products on the surface of the filter system without an additional power source and can operate by the wind power in the duct.

[0004] However, it is found in actual use that: the device drives the transmission rod and the brush plate to rotate by the wind-driven propeller, so as to clean the dust on the filter pad, and to avoid the dust from blocking the filter pad and affecting the air circulation.

[0005] The ventilation direction of the ventilation device is blowing towards the indoor, and the main purpose is to introduce fresh air into the indoor to maintain good air quality and a suitable indoor environment. However, when the brush plate cleans the dust on the filter pad, part of the dust will be brushed off and blown into the indoor along with the wind. In this way, the air blown into the indoor will carry dust, which not only affects the indoor air quality, but also may adversely affect the personnel present. Therefore, an indoor ventilation device for a stadium is provided. UTILITY MODEL CONTENT

[0013] In summary, due to the adoption of the above technical scheme, the present application has the following beneficial effects:

[0014] 1. In the present application, due to the adoption of the above scheme, the main drive shaft of the double-shaft motor is started to drive the fan blade to rotate, so that the external air is filtered by the filter screen and then enters the interior of the stadium to complete ventilation and air exchange. When the main drive shaft of the double-shaft motor stops rotating, the vice drive shaft drives the installation block and the brush plate to rotate, so that the brush on the front side of the brush plate cleans the inside of the filter screen.

DETAILED DESCRIPTION

[0021] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0022] REFERENCE Figures 1-5 A ventilation device for indoor of stadium, comprising a ventilation duct 1, the ventilation duct 1 is made of galvanized steel plate material; the ventilation duct 1 is made of galvanized steel plate material, the galvanized steel plate has a certain hardness and good waterproof and corrosion-resistant performance, so that the ventilation duct 1 will not appear corrosion and rust during long-term use, and the service life of the ventilation duct 1 can be improved.

[0023] In some embodiments, a filter screen 2 is arranged inside the ventilation duct 1 close to the left end, a limiting ring 3 is fixedly installed on the inner wall surface of the ventilation duct 1, the rear side of the filter screen 2 is fitted with the front side of the limiting ring 3, and a limiting mechanism 4 is arranged at the left end of the ventilation duct 1; the filter screen 2 is arranged to facilitate filtering the air entering the indoor of the stadium, and the limiting ring 3 is arranged to facilitate limiting the filter screen 2, so as to facilitate subsequent installation and fixation of the filter screen 2.

[0024] In some embodiments, the limiting mechanism 4 comprises a mounting plate one 9 and a limiting plate 10, the mounting plate one 9 is fixedly installed on the outer surface of the left end of the ventilation duct 1, and a plurality of limiting plates 10 are fixedly installed on the front side of the mounting plate one 9 through bolts; when one side of the filter screen 2 is fitted with one side of the limiting ring 3, at this time, a person can screw the hexagonal bolt into one side of the mounting plate one 9, so as to facilitate installation and fixation of the limiting plate 10, so that the side of the limiting plate 10 can press the one side of the filter screen 2, and installation and fixation of the filter screen 2 are realized.

[0025] In some embodiments, the inside of the ventilation duct 1 is fixedly installed with a double-shaft motor 5 near the middle, and a fan blade 6 is fixedly installed on the right driving end of the double-shaft motor 5. The double-shaft motor 5 is arranged to drive the fan blade 6 to rotate, so that the air outside can enter the indoor sports venue after being filtered by the filter screen 2, thereby achieving ventilation of the indoor sports venue.

[0026] In some embodiments, an installation block 7 is fixedly installed on the left driving end of the double-shaft motor 5, and two brush plates 8 are fixedly installed on the outer surface of the installation block 7. The double-shaft motor 5 has two driving ends, one of which is the main driving end for installing the fan blade 6 to ventilate the indoor sports venue. When the main driving end stops rotating, the auxiliary driving end, i.e. the left driving end of the double-shaft motor 5, starts to drive the installation block 7 and the brush plate 8 to rotate. The brush on the front side of the brush plate 8 cleans the filter screen 2 from the inside, so that the dust after cleaning can be discharged through the front side of the filter screen 2, improving the cleaning efficiency. Moreover, the dust will not enter the indoor sports venue when the brush plate 8 is cleaning. The double-shaft motor 5 has the function of controlling the start and stop of the two driving ends. The double-shaft motor 5 has multiple models, which can be selected according to actual needs. The model of the double-shaft motor provided in this application is TRZ120-250-8.
